Answer» Cost function, ` C(x)=26000+30x` and revenue function, ` R(x)=43x` For profit, ` R(x) lt C(x)` `rArr 26000+30x lt 43x` `rArr 30x-43x lt - 26000` `rArr -13x mlt - 26000` `rArr 13x gt 26000` ` rArr x gt (26000)/13` `:. x gt 2000` Hence, more than 2000 cassettes must be produced to get profit. |
